View Full Version : Stronger CAPTCHA?

Seems recently there have been several Spam/porno-bots on the board. Perhaps one way to stop this would be to strengthen the CAPTCHA used so they cant automatically sign up?

Agreed!

Maybe have one of the number, letter ojimafilps that not even real people can view!

You know like the boxes when you make a new email account.

:)

Edit: Put it when you make an account and when you post a new thread/post!

I reckon a captcha for new threads would be a good idea, but I'm not liking the ever post idea.

Also, I spoke to Day about this earlier. Is there any way of using a secure off-site CAPTCHA rather than one on site? I don't know much about vBoard so I'm not sure.

I know it will be a pain in the ass but it will save some space. Won't it?

Ok i thought this though. Maybe not posts but definitely threads.

Just came here to make such a thread, glad to see it's being looked at. What I have seen implemented to good effect previously on vbulletin boards is simply setting a post count limit before a user can make a new thread. (At either 5 or 10 posts)

Not perfect by any means, aside from minor frustrations (Personally I'm more frustrated by entering the codes) it may have new members spamming so they can make a thread, conversely it may stop people signing up and making a new thread straight off and hence perhaps using search more, especially if you indicate such in the error message they receive. I'm also not sure if bots can get around this yet, been a while since I last posted much on vbulletin boards.

Anyway, worth consideration in the discussion I think.

One thing that works but is a pain in the ass is make all accouts admin activated.

I had to do this on a board of mine but I got alot of spam in my e-mail about new accounts.

With this system an admin can view a few things before allowing them access to the boards. E-mail it's obvious if it's a bot because most of the time the e-mail is something really stupid like @stupidurl.com and the location is usually somewhere like Africa or Asia.

As I said it's a pain but it works.

I think that banning the bots is easier than making EVERY member sign-up go through the admins.

Im sure its possible to make the CAPTCHA more complex using the bulit in tools in the forum software. Im sure that if it was made more complex the bots would struggle to crack it

I think the bots are "equipped" with random code generators or something that are set to the specific type of CAPTCHA...

Some CAPTCHAs use a 3 number/letter image that is pretty easy to read and guess. Other ones, use up to 12 letters and numbers. (that I've seen, anyway)

I don't really like the idea of using a CAPTCHA on each thread. That's just annoying. If you can stop the bots before they even get on the site, no need for that thread CAPTCHA.

I think the 5 or 15 post limit before being allowed to make new threads is a good idea, though. Seriously... some people join the site and emediately make five threads in different game forums asking practically the same questions.

"How hard are these achievements" or something to that effect. Very annoying.

Skillet speaks the truth. I agree with the post limit before making a thread idea. It would stop a lot of the spam and porn spam on this site.

Yeah that would be a great idea, having a post req. It would be very annoying having to put in a bot-proofing thing every time you post.

@ Night: I think it is possible to use captchas from other sites, as I have seen many forums using vBulletin software that have custom captchas.

The other positive effect that would would have is it would keep people from coming on, registering an account, and then making a "HAI GUYS WANNNA BOOOST HALO?" thread without looking anywhere on the site. Maybe, just maybe, reduce the number of redundant threads that get created?

Yeh but then that way people are just going to post meaningess crap messages just to get there number up, so they can make a thread. Will have anther problem of hundred of worthless posts then.

Exactly.

Approve!

That may be true, but if it's bad enough, the mods will step in and deal with it appropriately. That, and junk posts can still have some sort of contribution, however small, to the conversation. That's rarely the case when someone comes in and starts making new junk threads to up their post count.

Glad everyone sees the merits (and, indeed, cons) of it. :)

However all those aside, as I said, bots may have developed so they can bypass it, no real need to implement anything of that's the case as it would be somewhat redundant. Likely need to look into it on the vbulletin boards to see what the latest advances are, there are generally pretty good on mods, anti-bots, security etc. from what I understand.

Theory my friend Theory... It doens't work they have rotating ip's. Plus they post once and that one never posts again.

Here's an idea. Make it to where members can't start a thread until they made 10-20 posts...

EDIT: I'll ask a friend of mine what he does to prevent auto spammers. (He's the site admin at a BF2 Tournament I used to be apart of)

Well, how about this theory.

Users must have one post to post in any forum other than the Introductions Board. To make a new topic in that board the user must fill out a CAPTCHA. A PM is sent out on registration telling the user that they must make an intro thread to take part in the community. This has the advantage of A: Giving the bots a lot of hassle and B: Making all users introduce themselves

The number of threads that would go into that one forum would become absurdly unwieldy, I think. I'm not certain, but I'd imagine that it would take a LOT less work just to set a post minimum to be able to start new threads.

I've run tonnes of communites before and run a few now. Bots are definetly a pain in the butt, but as suggested here there are ways around it. If the owner of this site heads over to www.vbulletin.org they can sign up there and download modifications for vbulletin. There are at least 5 available for this version which are to do with improving the CAPTCHA system and making it tougher for bots to crack, There are even ones where you create your own question which a user has to answer to continue registering. Such as "What is 1+1" or simple things like "Type hello in the box below".

I had about 5 bots signing up each day, and now i have none due to putting these into action. Hope it helps.
